PATENT RALPH 1. TUTTLE, OF NEW YORK, N. Y.

SEMAPI-IORE-SIGNAL DEVICE.

Application filed April 26, 1913.

To all whom it may concern:

Be it known that I, RALPH I. TUTTLE, a. citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements inSemaphore-Signal Devices, of which the following is a specification.

My invention relates to semaphore signal devices, and particularly tosemaphore signal devices used in connection with railway signalmechanisms. An object of my inven tion to provide for a light weightblade which can be easily attached and detached to the semaphorecasting. I will describe a semaphore signal device embodying myinvention, together with a modification thereof, each embodying myinvention, and then point out the novel features thereof in claims.

In the accompanying drawings, Figure 1 is a side elevation of a signaldevice embodying my invention. Fig. 2 is a top plan view of the deviceof Fig. 1. Fig. 3 is a vertical sectional view taken on the line 3-3 ofFig. 1, but drawn to a larger scale. Figs. 4 and 5 are detail views, thelatter being a sectional view taken on the line 55 of Fig. 1. Fig. 6 isa view similar to Fig. 1, but showing a modification. Fig. 7 is a topplan view of the device shown in Fig. (3. Fig. 8 is a vertical sectionalview taken on the line 8-8 of Fig. 6, but drawn to a larger scale.

Similar letters of reference designate corresponding parts in all of thefigures.

A designates what is termed in the art as a spectacle casting, which, asusual, carries colored glass disks (not shown) and is provided with whatis known as a blade grip a. The casting A, as usual, is mounted on ashaft which is operated to move the casting, and with it, the coloredlenses and blade, against the usual bias of the casting and blade. Theform of invention shown in the drawings is adapted for use in connectionwith semaphore signal devices, the indications of which are given in theupper quadrant, though my invention is equally applicable to signaldevices which indicate in the lower quadrant.

B designates a supporting piece, preferably of metal, and here shown asbeing T shape in cross-section, which is suitably rigidly connected withthe blade grip of Specification of Letters Patent.

the casting A. The piece 13 is also to add strength to the blade, whichis supported therefrom. The piece B may be rigidly connected with thecasting by any de sired means. It is shown as being connected with theback of the blade grip, and in Fig. 1 the piece B is retained inposition between two pairs of opposed plates 7), Z), which are held bybolts Z2 and nuts 6 This is best shown in Fig. 3. In Fig. 6, the piece Bis rigidly connected with the back of the blade grip by means of a Ubolt 6*, the ends of which are threaded to receive nuts 7), and by abolt Z) and nut Z2 which passes through the piece B and the blade grip.

C designates a signal blade which is adapted to be supported from thepiece 15. This is accomplished by means of a strap 0 (here shown asbeing in the form of a pocket) secured to the blade into which the endportion of the piece B extends (see Fig. 5) and clips 0, 0 also securedto the blade which engage with a cross piece 5 (see Figs. 2 and 1)secured to the piece B. The blade may also be connected with thespectacle A, (if necessary) by any desired means. As shown in Fig. 1,these means comprise the ends of the bolts Z2 which extend throughopenings in the blade C and nuts 7), suitable fiber or other washers 6are employed on both sides of the openings in the blade. In Figs. 6, 7,and 8, the means are the end of the bolt Z) which extends through anopening in the blade C, and a nut 5 washers 5 are also employed on bothsides of the opening in the blade.

The blade C may be of wood or metal. The blade shown in the drawings isof metal, with the longitudinal edge portions bent at an angle, in orderthat the blade shall be stiffened, and to prevent the edges of the bladewarping during heating in case the blade is enameled.

In the form of invention shown in Figs 1 and 2 the blade is slightlysprung when it is placed on the supporting pieces, whereas in the formof invention shown in Figs. 6 and 7, the supporting piece 13 is offsetat that portion adjacent to the blade grip, so that there is no need ofspringing the blade when it is placed in position on the supportingpiece.

All that is necessary to place the blade in position on the supportingpiece is to pass the strap 0 over the end of the supporting adaptedpiece B until the clips 0 engage with the cross-piece 6 The blade isthen held in position by means of the bolt or bolts passing through theopenings.

Having thus described my invention, what I claim as new is:

1. A railway signal device, having in combination, a spectacle casting,a blade, a piece B from which said blade is slidahly supported, andindependent means for connecting said supporting piece with a spectaclecasting.

2. A railway signal device, having in combination a spectacle casting, ablade, a piece 13 from which said blade is slidably sup ported, meansfor connecting said support ing piece with said spectacle casting, andindependent means for connecting the blade with said spectacle casting.

3. In a railway signal device, the combination of a spectacle casting, asupporting piece carried thereby, a blade, and means for remowablysupporting the blade from said piece, said means comprising a. partcarried by the blade and engaging the end portion. of said piece, andanother part also carried Copies of this patent may be obtained for bythe blade and engaging with apart carried by the supporting piece.

el. In a railway signal device, the combination of a spectacle casting,a supporting piece carried thereby, a blade, and means for reniovablysupporting the blade from said piece, said means comprising a partcarried by the bladi and engaging the end portion of said piece, and twoother parts also carried by the blade and engaging with a part rarriedby the supporting piece.

5. A, railway signaldeviee comprising a spectacle, a supporting piecesecured thereto, a substantially fiat signal blade, a strap carried bythe blade and engaging the end portion of the supporting piece and clipsalso secured to the blade and engaging with the supporting piece wherebythe blade is reinovably supported from the said piece.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribed witnesses.
